Everything you need to know about non-invasive prenatal testing

How Non-Invasive Prenatal Testing Works

If you decide to have non-invasive prenatal testing, we will take a small sample of your blood. Most of the cells in this sample will belong to you, but there will also be some fetal-placental cells circulating in your bloodstream. We can isolate this cfDNA and check them for certain genetic or chromosomal abnormalities. We can even separate out the cells of your babies to test them individually if you are expecting twins or more.

Who Should Have Non-Invasive Prenatal Testing?

We may recommend NIPT if:

  • Ultrasound scans have detected a concern with your baby’s development and we want to confirm whether there is a chromosomal condition such as Down’s syndrome
  • There is a chance that your baby could have inherited one of the genetic disorders that we can test for, such as thanatophoric dysplasia or achondroplasia
  • There is a chance that your child could inherit an X-linked disease if he is a boy, so you want to find out the gender before it is possible with ultrasound

What the Results Mean

The results of NIPT are highly accurate. Since we are looking directly at your baby’s genes we can be sure whether he or she is carrying a chromosomal condition. 

If a problem is discovered during NIPT your consultant will help you to understand what it means for you, your baby and any future pregnancies.
